Experimental investigation on the structural performance of square hollow glass columns under axial compression
This paper presents an experimental study into the global behavior of glass columns with square hollow cross-section under axial compression. In the research, totally 6 specimens were tested. All specimens were of the same geometry (length 750 mm, width 150 mm and 10 mm) but had different compositi...
